NWSB Insider and Seattle Mariners’ blogger Brian Scott talks about the recent call up to the Mariners for Taijuan Walker, pitcher extraordinaire. Jack Z and Eric Wedge can’t wait anymore. They want to see what he can do in the bigs. Brian says Yes, he’s only 20 years old, but let’s not forget that a once very young Felix Hernandez made his major league debut at 19. Brian firmly believes Taijuan is ready.
